Mastervolt Terminals

Hi - one of our batteries died on Tuesday and we have just replacedthe lifeline AGMs with mastervolt AGMs. This is largely because that's what's available here in ar easonable time (here is Caligari, Sardinia). We can either pay an electrician EU120 (and spend 3 extra nights in a marina) or connect them ourselves.

The basic arrangement is easy - BUT we find that the terminal on the battery looks very different from the straightforward standup terminals on the lifelines.

So can anyone help by advising how you attach a cable to the terminal? We've looked on the mastervolt site, which makes it look as if the terminal, which is a thick stud, should in some way pop up so you can slip the ring at the end of the cable over it.

Thanks in advance for any help.

You can normally find an adaptor terminal that will clamp on/screw on/attach somehow to the Master batteries. The Mastervolt website shows a whole page of terminals to connect the batteries to your existing cables. It appears that Mastervolt batteries have the standard lead round stud which is clamped/squeezed by the terminal. These are a very common style attachment system.
- - One tip on keeping the connections good for a long time is to clean the battery terminals and the adaptor terminals very well. Then after all the cables and stuff are tightened down get some "liguid" electrical tape and paint a thick coating of it all over, around, and under the terminals. This is to keep any gases from eating at the terminals and making the "white" powder corrosion which leads to eating away the connections. Keep painting on layers of the liquid electrical tape until you have a thick coating.

Hi and thanks. Actually when Pip came back and we looked at the manual together she immediately saw that it's easy to connect by taking the outer case off using an allen key. New batteries now installed and working thanks. We hope to leave Cagliari tomorrow - rather poorer than when we arrived!
